Abstract

A device includes a container for accommodating a medicament, a pressure route and a valve. The pressure route, disposed in the container, includes an extending pathway, a pressure-route inlet connected with a connecting port, and a pressure-route outlet extending toward a container bottom. The valve includes a first through hole connecting spatially the pressure-route inlet and outlet, and a valve body dividing the extending pathway into a pressure-in pathway and a pressure-out pathway. The device can convey the medicament such as a hemostatic agent more stably and smoothly to effectively avoid blocking upon a field of vision of an endoscope by the disturbed medicament while hitting a target tissue. Thereupon, the medicament can be provided more precisely, continuity of an endoscopic surgery can be improved, efficiency of hemostasis can be enhanced, and also surgery time can be substantially shortened.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A medicament delivery device, comprising:
 a container, used for accommodating a medicament; 
 a pressure route, including an extending pathway, a pressure-route inlet and a pressure-route outlet, the pressure-route outlet extending toward a bottom of the container; and 
 a valve, including a first through hole and a valve body, the first through hole connecting spatially the pressure-route inlet and the pressure-route outlet, the valve body dividing the extending pathway into a pressure-in pathway and a pressure-out pathway. 
 
     
     
       2. The device of  claim 1 , wherein the device further includes a connecting port disposed at the container, the connecting port is used to connect a pressure source, and the connecting port is connected spatially with the pressure-route inlet. 
     
     
       3. The device of  claim 1 , wherein the valve body further includes a guide member for having the pressure-out pathway and the pressure-in pathway to extend toward the first through hole. 
     
     
       4. The device of  claim 1 , wherein the valve body changes at least once a flow direction of a fluid along the pressure-out pathway. 
     
     
       5. The device of  claim 1 , wherein the valve body changes at least twice a flow direction of a fluid along the pressure-out pathway. 
     
     
       6. The device of  claim 1 , wherein, after the valve body changes at least twice a flow direction of a fluid along the pressure-out pathway, the fluid in the pressure-out pathway flows toward the pressure-route outlet. 
     
     
       7. The device of  claim 1 , wherein the valve body further includes a first turning member disposed inside the pressure-out pathway to turn a flow direction of a fluid in the pressure-out pathway for a first time. 
     
     
       8. The device of  claim 7 , wherein the valve body further includes a second turning member disposed inside the pressure-out pathway to turn the flow direction of the fluid in the pressure-out pathway for a second time. 
     
     
       9. The device of  claim 1 , further including a fluid pressurized to flow along the pressure route, wherein the fluid is a gas or a liquid. 
     
     
       10. The device of  claim 1 , wherein the medicament is powdery and has more than 90% of powder particles with a grain size ≤100 μm. 
     
     
       11. The device of  claim 1 , wherein the medicament is powdery and has more than 90% of powder particles with a grain size ≤50 μm. 
     
     
       12. The device of  claim 1 , wherein the medicament is a hemostatic agent.
